Send parameters to a web service.
- by Alejandra Meraz
Before I start: I'm programming for Iphone, using objective C.
I have already implemented a call to a web service function using NSURLRequest and NSURLConnection. The function then returns a XML with the info I need.
The code is as follows:
NSURL *url = [NSURL URLWithString:@"http://myWebService/function"];
NSMutableURLRequest theRequest = [[NSMutableURLRequest alloc] initWithURL:url];
NSURLConnection theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
i also implemented the methods
didRecieveResponse
didRecieveAuthenticationChallenge
didRecievedData
didFailWithError
connectionDidFinishLoading.
And it works perfectly.
Now I need to send 2 parameters to the function: "location" and "module".
I tried using the following modification:
NSMutableURLRequest theRequest = [[NSMutableURLRequest alloc] initWithURL:url];
[theRequest setValue:@"USA" forHTTPHeaderField:@"location"];
[theRequest setValue:@"DEVELOPMENT" forHTTPHeaderField:@"module"];
NSURLConnection theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
But it doesn't seem to work.
I'm doing something wrong? is there a way to know if I'm using the wrong names for the parameters (as maybe it is "Location" or "LOCATION" or it doesn't matter?)?
or a way to know which parameters is the function waiting for...
Extra info:
I don't have access to the source of the web service so I can't modify it.
But I can access the WSDL. The person who made the function say is all there... but I can't make any sense of it .<
Any help would be appreciated. :)
